Subject: [gforth] NOT
Any idea how to implement the word NOT in gforth to create a 1s complement?
I can find an assembler definition in SwiftForth, but no other luck anywhere.
I also don't seem to be able to find the assembler registers used by gforth.
Either I'm blind, or it is not documented anywhere.
TIA,
Dave in Hudson, FL
